PEGG lNG-JACK.

-SPECIF1CA'1ION forming part of Letters Patent No. 431,168, dated July 1, 1890.

Application filed March 26, 1890. Serial No. 345,449. {No model.)

To all whom it may concern.-

Be it known that I, RICHARD E. KIDDER, a citizen of the United States, and a resident of Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Pegging-Jacks, of which the following is a specification,accompanied by drawings forming a part of the same, and in whichv Figure 1 represents a side view of a peg ging-jack embodying my invention supporting a last which is represented in rear or heel view. Fig. 2 represents a top view of the last shown in Fig. 1 as supported upon the jack, and showing the end of the stem of the last. Fig. 3 represents a top view of the upper end of the post or standard upon which the last is supported, and shows a view of the bottom of the socket, in which the stem of the last is placed. Fig. 4 is a side view of the jack with the post or standard tipped into a horizontal position. Fig. 5 represents the jack with the standard tipped into a horizontal position, as shown in Fig. 4, but showing the bottom of the last, the view being taken at right angles to the view shown in Fig. 4. Fig. 6 represents a View of the standard of the jack, but with a modified form of stop, by which the rotation of the last is limited. Fig.

c 7 is a top view of the last, showing the form of stop illustrated in Fig. 6. Fig. 8 shows a top view of the socket in which the stem of the last is placed; and Fig. Qrepresents a portion of the jack, with a rotating joint within the body of the standard itself andindependently of the last, which is supported upon the rotating section of the standard.

Similar letters refer to similar parts in the different figures.

My invention relates to a pegging-jack de signed to be used with an iron last; and it consists in the arrangement of a stop by which the last is limited in its rotation and held in a horizontal plane, inorder to allow the edge of the boot or shoe to be finished.

The jack forming the subject of my invention is principally designed for the use of repairers; and it consists of a post or vertical standard A to support the last B, with the bottom of the last in a horizontal plane, in which the boot is pegged. The post or standard A is bent or curved between the base A and the top A to allow the strap B to pass from the boot held upon the last downward to the base upon one side of the top A and as the last is rotated in the standard to pass around the end A as hereinafter described. The lower end or base A is extended laterally and pivoted at C to the fixed support 0', allowing the standard A to be tipped into a horizontal position, as represented in Figs. 4 and 5, bringing the bottom of the last into a vertical plane and presenting the edge of the boot upon the last in ahorizontal position, as represented in Figs. 4 and 5. The last 18' is capable of rotating about an axis coincident with the axis of its stem D, which is preferably made cylindrical, and is held in a socket E in the top A of the standard A. The end of the stem D entering the socket is provided with a projecting spur a, occupying nearly or quite one-quarter the area of the end of the stem, and the bottom or end wall of the socket is provided with a similar projecting spur b,

the spurs upon the stem and the end wall of the socket being so arranged that they will be brought into contact when the last is placed in a position with its edge horizontal, as shown in Fig. 5 of the drawings, affording a rigid support to the stem D to hold it from further rotation, in a direction which would carry the toe G of the last downward, and offering a rigid resistance to any pressure exerted upon the edge of the boot or shoe held upon the last. As the edge II is finished,the toe of the last B is raised, thereby rotating one-half a revolution and brought into the position indicated by the broken lines 13 bringing the opposite edge 11 of the boot or shoe uppermost and in a horizontal'position to be finished, the projecting spurs a 1) upon the stem and in the socket serving as a rigid stop to sustain the toe of the last from downward movement as the edge H is being acted upon. If preferred, the projecting spurs can be arranged upon the end of the standard atc and upon the shoulder I of the last at (1, instead of the end of the stem andin the bottom of the socket, as described. In some cases such a disposition of the spurs forming the stop might become desirable, in order to relieve the stem of torsional strain. I do not therefore confine myself to the special disposition of the spurs, but the modified construction I have represented in Figs. 6,7, and 8. If the stem of the last is other than cylindrical, as is sometimes the case, the stem can be inserted in the upper end of the standard and the standard itself can be formed in two sections, the lower section J, Fig. 9, being non-rotatable and the upper section J, supporting the last, being rotatable. The stop constructed substantially as described can be interposed between the rotating and non-rotating sections J J of the standard at the point J Fig. 9.

In the use of a pegging-jack in the manufacture of boots and shoes, as their manufacture is generally carried on, the edges of the boot are finished after the removal of the boot from the jack by means of appropriate machinery, and the rotation of the last in the jack for the purpose of finishing the edges of the boot is not deemed necessary. In repairing or hand-making it is, however, of great advantage to not only rotate the last in the jack, but also to sustain it in the positions represented at B and B by solid and broken lines in Fig. 5, so as to maintain the edges II and II in a horizontal position under the pressure applied in the process of finishing the edges of the boot.

There are many obvious modifications of the devices, by which the rotation of the last is so limited as to hold the last in the two positions indicated in Fig. 5, aside from those already described and shown in the drawings, and such modifications would,in my opinion, fall within the scope of my present invention, the essential feature of which is to provide such a stop between the non-rotatable portion of the standard and the last as to limit the rotation of the last to one-half a rotation and bring the edges upon the sides of the bootviz., H and I*I'-into a horizontal position, as shown in Fig. 5, and to maintain the last in such positions against the pressure applied in finishing the edges of the boot.

The strap by which the boot is held and the means employed to tighten the same form no part of my invention, and therefore I have not described them in detail. The tightening is effected in the form of jack represented in the drawings by means of a pivoted lever K, to which the end of the strap B is attached, the strap being carried from the last 13 over rolls to change its direction to the lever K, which is held in position by a ratchet-toothed bar K engaged by the edge K of the lever. The standard A is offset in order to bring the lower end of the strap B into a line coincident with the axis of rotation of the last, which permits the strap to be carried around the upper end A of the standard as the last is rotated, as represented in Fig. 5.

I am aware that jacks have been heretofore known in which the last has been capable of rotation either upon its stem or by the rotation of its standard. Such I do not claim, broadly; neither do I claim, broadly, the employment of a device by which the last is held and forth in opposite directions between the two positions of the last without any change in or manipulation of the stopping mechanism. I am also aware that it is not new to construct pegging-jacks with a hinged seetion,whereby the last is brought into a position with the sole of the last in a vertical plane, and I do not herein claim such a construction; but

What I do claim, and desire to secure by Letters Patent, is-

1. In a pegging-jack, the combination of a standard provided with a socket, a last-supporting stem held by and capable of a limited rotation in said socket, a spur projecting from and carried by said rotatable stem, and a spur projecting from said standard and placed in the path of said movable spur, whereby the rotating stem is limited in its rotation to onehalf a revolution in either direction, substantially as and for the purpose set forth.

2. In a pegging-jack, the combination of a post, a supporting-standard hinged to said post and providedwith a socket, a last-supporting stem held in said socket, a spur projecting from said stem, a fixed spur placed in the path of said movable spur and in such relation thereto that the last is held with its opposite edges alternately in a horizontal plane and allowing the rotating 'last-support ing stem freedom of rotation through an arc of one-half of a revolution, substantially as described 3. In a pegging-jack, the combination of a post, a last-su pportin g standard hinged to said post and carrying the strap-tightening mechanism, substantiallyas described,whereby the last-holding strap is tightened, said supporting-standard being offset, so that the strap is brought into a line coincident with the axis of rotation of the last, said supporting-standard being also provided with a socket in which a last-supporting stem is journaled, a lastsupporting stem, a spur 011 said stem, and a fixed spur placed in the path of said movable spur and in such relation thereto that the rotation of the last-supporting stem is limited to one-half of a revolution, and the last held in a position with its sides alternately in a horizontal plane, substantially as described.
